U.S traveler sentiment index 2013
The Traveler Sentiment Index tracks changes in travel-related factors over time through the travelhorizons survey. The Index is tied to a March 2007 base. A value above 100 means that a higher percentage of respondents hold more positive perceptions about a particular attitude toward travel than those who feel negatively; a score below 100 reflects higher negatie attitude than positive.
The index is based on six indicators including: Overall interest in travel, demands on time available for travel, personal finances available for travel, affordability of travel, quality of service received and safety of travel in the United States.
